From: Masayoshi Mizuma <[email protected]> This kernel parameter allows to change the padding used for the physical memory mapping section when KASLR memory is enabled.
For memory hotplug capable systems, the default padding size, CONFIG_RANDOMIZE_MEMORY_PHYSICAL_PADDING, may not be enough. The option is useful to adjust the padding size.
